Herrold, Lancaster, `Pa, assigner to y Armstrong Cork Company," Lancaster, Pa., a corporation of Pennsylvania f Application Juney 24, 1937, Serial No. 150,()14 j e claims. (c1.` iss-7254 i f This invention ,frelatesfto display devices and 'more particularly to a device for the convenient and expeditious showing ofvarious and sundry surface` covering patterns in conjunction withsalesmen are consequently hampered in attempting to show color schemes and pattern effects with such materials. l l v According to the present invention, a threedimensional set in simulation of a room is constructed in miniature, with or. without provision for variations in color decoration, and a series of images of various patterned goodsis cast upon the surface of the set corresponding to the surface to-which the linoleum. or similar surface covering is to be applied. In this manner, a great number of different patterns and different colors may be viewed` with vlittle effort and no delay, and in addition, artistic fioors not in commercial production, but available for `cus- 30v tomers on order, may be displayed at little cost and effort. If one of the latter type of floors should be selected b y the prospective customer, the projecting device, or one similar, used to show the image of such floor, may be. used to project the image to large scale, wherebyl artistic designs and 'unusual combinations not customarilyr availablaand not readily occurring to the ordinary flooring contractor or dealer, may be readily duplicated by merely showing the image to full scale, enabling the layer or flooring con- 50 away of a different form of my display device;

and

, Figure 3 shows a further modification in sectional side elevation.

Referring first to Figure l, there is shown a 55 front wall 2 having an opening therein through tractor to mark the goods directly to the properwhich is visible a Vset 3 having the suggestion of windows and a door vto give scale to the set and having a reflecting surface 4 on the floor thereof upon which is projected an image of a floorv covering by a projector 5 {which throws 5 the image from a film 6 upon, an angularly adjusted mirror 1 to the surface.l .The mirror 'l is adjustable vto permit centering of the image on thesurface *and the film k6 may be traversed through-.the projector in a step by step man- 10 ner tos-how the effect of different floor patterns in combination-with the set 3. In Figure 2,;I haveshown an arrangement in whichitj ispossible'to havev model furniture s in the Sem', vinasnmch:as"une image-'of the 15 fiooring material is projected from a film 6' by a projectoriv upona mirror-1f against a translucent screen 9, thewholeof the set being viewed through an opening in thewall` 2'. The film 6 is ktraversed lwith a remote control Ill by the 20 operatora't will. VVarious patterns may be shown withtheminiature furniture 8 moved about at Will without'disturbing the limage of the floor.'

In Figure 3, I have shown a further arrange- Ament in'which a projector 5" is arranged verti- 25 cally to cast an image lupon an inclined surface il. The advantages of inclining the surface Il are that it makes `the image more readily observable through an opening in the wall 2", and that the back part` of the surface Il, indicated at b, being higher than the front part of the surface Il,y indicated at yf, will cut the stream of light projected from the projector 5" closer to the focal point, whereby the image will be somewhat smaller at b than at f. Thus, the floor 35 as viewed through the opening in the front wall 2 will exhibit a feeling of perspective, and the side walls, one ofwhich is indicated at s may be moved 'closer together at/,the back of the display device than they are at the front of the 40 display device, heightening the feeling of perspective rwithout cutting the image on the surface Il.

My invention contemplates the employmentv of a non-planar mirror inthe arrangement shown in Figures 1 and 2 to provide the projection of the image of a floor which is narrower at the back of the display device than it is at the front. I prefer this method inasmuch as thelm from which the vprojection is made is thus capable, when used without suchy mirror, of projecting a flat geometrically symmetrical image, enabling the contractor or layer to readily lay out full sized floors, which may have beenselected for installation, by merely casting the u appropriate image to the scale desired upon the material to be used and marking the same from the image so cast.

My device, of course, may` be used to equal advantage in displaying wall or ceiling coverings,

and the principles of operation herein set forthI will enable its ready..adaptation to such use. When used in displaying floor coverings, the side Walls of the set (such as shown at s), may, of course, be Varied or used interchangeably in various colors to demonstrate color combinations.

While I have illustrated and describedcertain preferred embodiments of my invention it will be understood that the invention is not so lim-` ited but may be otherwise embodied Within the scope of the following claims:

I claim: v 1. In a display device, a projection cabinet hav'- ing. a face panel with an opening therein, a miniature room formed in said cabinet and having substantially closed vertically arranged back and side wall areas and a planar, translucent unobstructed by and extend under miniature furing and converging toward `said back wall area,

projection means mounted in the cabinet including a lightsource, an image carrying transparency and a nonplanar mirror eiective for distorting an image projected from said transparency to cause 4the same to assume a. trape- Zoidal shape corresponding to the shape of said oor area whereby the image when viewed through the opening will exhibit a feeling of perspective. 7

3. A displayv device in accordance .with claim 1 in which the means for projectingthe floor-coveringr designs onto the vtranslucent floor area comprises projection means'mounted in the cabinet including a light source, an image carrying .transparency and a nonplanar'mirror 'effective for distorting an image projected from said transparency to causev the same to assume a trapezoidalshape whereby the image when Viewed through the opening `will exhibit a feeling of perspective. j i y WALTER W.
